'MAN and EDWARD E. EUCHENHOFER, citizens vof the United States,

have invented certain `new and useful Im'- l on the line 6, 6, of Fig.14;

taken on the line 3, 3, of Fig. 1.

the following isa specification, reference being had therein to theaccompanying drawings.

This invent-ion relates to certain new and;l Auseful improve-ments 'inAmachines for wrap; ping'or enveloping candy, either in the formv 4ofdrops or sticks,

` -tion of the core is substantially Fig, 5, a longitudinal sectionalFig.' 6, isa

- `The letter A designates the bed or topol ourmachine. It is mountedupon legs B,

ypreferably connected together bybase rails C. On the bed plate A aremounted standards D whichsupport a drum E- on which is wound andsupported along strip of paper F which passes under guide-bars .G andover a guide-bar H, all supported in a frame I on, DAYTON, onto.

mounted on the bed piece. l Collars J, held by set screws, serve'toguide the paper strip by engaging with its edges. -The collars may beset in or out to agree with the Width of the strip. (See Fig. 1.)

Secured to the frame I,is a guide core K, preferably made ofsheet metaland curved in the Iirstportion of it so `as to guide the paper stripsmoothly under it. The crosssecsemicircular, as suggested in Figs. 1vand 5, and clearly shown in Fig. 6. About the point where the curve ofthis core terminates, commences the paper guide conduitL also preferablymade cular cross section, as suggested in Figs. 1, 2 and 5 and clearlyshown in Fig. .6 and other detail figures. andthe guide conduit L isleft suicient for the ready passage ofthe paperstrip. -The guide conduitextends to the point M where it is formed into a tube.

`J ustbefore/the part place' in the conduit whatwe term the hopper whichis shown at O, Figs..1, 2, 3, and 16. This hopper see Fig. 16 issubstantiallya tube,

A space between thecore K 'f M of the conduit, we f being'cut open ateneside and having its edges flared ont to'form an opening P for receivingthe candy or other articles. The remainder of the hopper, the tubularpart, projects onward in the conduit. 'lhe hopper is provided with abracket Q which spans the conduit and tits upon the bed-plate where itis detachably secured by spring latches R.

- Thus the hopper issupported in the conduit with a space between thehopper and conduit for the passage of the paper just as is the casebetween the guidecore K and the conduit.

At S a sleeve is placed over the conduit, the sleeve being openas seenin Fig. 13 so that it can be sprung to slip past the tubular part IOO.

. 75 of sheet metal and of substantially semicir- M of the condui-t.This sleeve performs two functions, first, that of engaging with the upper projecting edges of the paper strip and turning them toward eachotherso section into a tubular form as it passes between the hopper andthe conduit at the point where the sleeve S spans or encircles theconduit; secondly, the function of the sleeve S is to support springarms T which carry at their other ends, theoverlapping jaws U therebyforming what we term the article holder. These overlapping jaws U holdthe article after the paper is about it, while, in the initialoperation, the

blank is disposed of, andwhile the paper of the first article is beingtwisted, these jaws hold the second wrapped article, and so on as the-machine is operated.

Now in order to project th article along from the mouth of thehopperthrough the tubular part of the hopper and thence into the papertube, which latter is shown at V, being that part of the strip from thesleeve S to the end of it in the direction of the right hand as viewedin Figs. 1 and 2, weprovide a feed rody or plunger W which reciproeatesin the conduit and through the hopper so as to force the articles frpmthe hopper into the paper tube to about the point indicated at X in Fig.2. The plunger is reciprocated, preferably by means of a bell cranklever Y, with which it engages as seen at d a cam-mechanism and elevatedby a sprin g c, as will hereinafter appear, so that the plunger isautomatically and regularly reciprocated,

The next mechanism to operate in the machine is the reciprocatinggripping device. This consists of a head d, mounted in ways e, of thebed A,and carrying a sleeve or hollow shaft f, rotated by a flange g andpins h, which are engaged by pins fi, carried by a pulley j, operated byalbeit b" and mounted on a hollow shaft or sleeve l mounted in astationary head m, itself secured in a fixed position by a set screw oin the ways c of the bed A. Thesleeve or hollow shaft f has pivotedtherein two grippersp and q the enlarged inner ends of which arerespectively notched to receive the knobs lr and s of the yoke t,forming a part, of the gripper shaft u, mounted in the f and l. closethe grippers.

This shafty operates to open and Referring to Fig. 12 it will be seenthat the grippers are closed. Let it be supposed that they arekto beopened and that the sliding head d is/to be advanced so that thegrippers can take hold of the projecting end of the paper, as seen inFigs. 8 and 9. The shaft lwis frictionally held bythe friction clamp fu,w, mounted in the hollow fixed standard s'. When the head d advancestoward'the paper paper blank ahead of theV article is being twisted.-When this paper.

This done the shaftuisthrown -strip is changed from a gutter form in cross through the clamp,the spring c acting on the collar d assisting in moving the rod throughthe clamp..` When" the grippers arrive at the paper they are to beclosed from the position shown in Fig. 9.to that shown in Fig. 8. This`is done when the head d returns and draws the grippers against theknobs fr and s. This done the further return movethe grippers to pressharder and harder against the knobs, the tendency beingto make thegrippers bite harder and harder upon the paper. hen the pressure of thegrippers against the knobs overcomes the friction in the friction' clampand the tension of the spring c', the shaft u moves back with the head.The paper tube is, during this return movement of the lhead andlgrippers, being drawn out L and the holderU sothat by the time the headd is at its returned. position the paper and contained article haveassumed the position shown in Fig; 8. At'this time also the pins h arebeing engaged by the` pinsz' and the grippers rotated so at each side ofthe article, Fig. 8. -n

The next device to come into operation is the shears or scissors bywhich the `paper is clipped. This device consists of two pivoted bladese', f which act like scissors, their pivot being fastened in a suitablepart of the frame, say the upper part of the bracket h'. The shears arelocated so as to clip that part of the twisted paper which is betweenthe arallowng a projecting end for the grippers to take holdof in the asalso shown in `next operation.

designates a plate having oblique slots j which receive the antitrictionrollers 7c' of the studs Z in the lower ends of 'the shear blades. Thisplate t" is carried by the reciprocating rod 'm' mounted in the bracketh' andY slotted at' its lower end, as seen at o to straddle the cam yshaft p. A spiral spring q presses against the bracket h and against acollar fr on the rod tm so as -todepress the rod and uickly close theshears, so that they will clip t e paper. A cam s" mounted on the shaftp' engages an antifriction roller t on a stud u' carried by liftedagainst the spring and the shears opened.` Thus the shears are operated,being quickly closed by the spring action and being opened by the camaction.

In describing the operating. mechanism it stated that the standard k,which supports the shaft p is slottedas shown at l in Fig. 11 so as toguide the rod b. It should also ave been stated that a standard m"supports the bolt o" of the bell# as to twist the paper the rod mwhereby the rod is of the conduit TCO - perhead returns to deedanything'that is to crank 'lever formed of this rod and the arm c". Theshaft p also carries a gear wheel e' which meshes with a pinion wcarried on the shaft w mounted in the bracket z,'which bracket is a partof the head m., A pulley a carried by the shaft drives a belt'b" bywhichthe pulley j is rotated to rotatey the grippers, as above stated.The head d is reciprocated simultaneously with the reciprocations of theplunger rod W by the arm c which is in eiect arigid extension of thepivoted rod b. In other words a bell cranklever is formed of the arm cand therod b. Motion is given this bell crank lever by the cam d mountedin the shaft p and engaging with an antifriction rollere fixed collars fon the rod or portion of said bell crank lever markedb. To compensatefor the arc described by the arm c" of this bell-crank lever the pin greciprocates in said arm see Fig. l12 and is pivoted to the head d. Theshaft p is preferably rotated by power applied to it through the pulleyh. But two devices remain to be mentioned, namely, the box 12 in whichthe articles are kept to form av supply chine; and thereceptacle j intowhich the wrapped articles drop, this receptacle being placedsuicien'tly at one side of the machine to catch the articles as they flyout of the machine on account-of their high rotary speed at the momentwhen the'paper is-clipped.

We have incidentally described the gperation of the machine inconnection with the above description of its mechanismg but in orderthat, it may be more lfully understood we would observe that in thefirst placethe paper strip is fed by hand before the machinev isstartedup, that is,.the initial feed i's done by hand. After that thepaper is drawn'automatically throfugh the conduitby the action of thegrippers when the Ireciprocating gripwhat may be called'the normalposition. The papel' having been fed in the first instance by hand, anarticle, say a candydrop, or a lemonor an orange or inbe wrapped, is

dropped ntothe hopper when it is projected by the plunger rod to theposition shown at X in Fig. 2. This done the gripper head advances yandthe grippers take hold of the projecting tubular-part of the paper anddraw out what may be called a blank, twisting and cutting it olf. Thisblank goes to waste, but

in drawing it out the paper is advanced iny the conduit until thearticle is moved along with the paper tube from thepoint X to within thespring holder U. nere it is had unu the gripper head again advances andtakes hold of the projecting end of the paper and draws the paper out,taking with it the con tained article. We have before stated that as thegri ppers advance to the paperthe plunger rod reciprocates toward thehopper. Therefore as one article is drawn from the point X another willhave taken its place, so that -cle is being wrapped by playing betweencle, and grippers to take -means to reciprocate and for feeding the ma-'with a conduit wh into the tubular as an article leaves the holder andenters the holder. Thus while oneartithetwisting process another is inthe holder and the paper tube .is beingclamped about it by the holder sothat the paper is held from rotation and from twisting by the holder,causing 'the twists to take place only in the unfilled part of the Shownin Fig.8. These operations'are repeated in rapid succession and thearticles are wrapped with great rapidity andwith uniformity, as has beenascertained by practical tests Aof this machine. l

Having thus fully described our invention, what we claim as' new, anddesire to secure by Letters Pate-nt, is-
